- Can you please pick the right answer in each parentheses? Cholesterol levels in human serum are determined by ["only biosynthetic rates", "a combination of endogenous synthesis, update from the diet, and excretion via bile"] . Inhibition of ["HMG-CoA synthase", "HMG-CoA reductase"] can reduce cholesterol levels, and reduces the formation of a 6 carbon organic acid, ["isopentyl diphosphate", "mevalonate"], that is a critical building block for cholesterol.Fill in the gaps (type your answers in all capital letters): Lactate fermentation is an important pathway, allowing the body to regenerate the co-factor in the absence of (molecule). During the process of cellular respiration, the enzyme converts pyruvate to acetyl-coA using five co-factors, including |(name one). Acetyl-CoA is a substrate of the ТСА сycle, where tior one acetyl-CoA one of the TCA cycle produces molecules of and 1 molecule of that function as electron carriers.Below are some statements about the TCA Cycle. Which statement is true based on what we have learned in the class? Question 16 options: Oxaloacetate can be replenished from pyruvate carboxylation catalyzed by pyruvate carboxylase. The catabolism of proteins can only feed into the TCA cycle at one point, which is Acetyl-CoA. Acetyl-CoA has transporter proteins and can be transported directly from matrix to cytoplasm (for fatty acid synthesis). In TCA cycle, both Acetyl-CoA and Succinyl-CoA hydrolysis reactions are coupled with ATP/GTP synthesis.
